Description of detection logic

IsImprovementBase: Marked as improvement because the compare was 5% less than the baseline, and the value was not too small.
IsImprovementCheck: Marked as improvement because the three check build points were 0.05 less than the baseline.
IsRegressionBase: Marked as not a regression because the compare was not 5% greater than the baseline, or the value was too small.
IsImprovementBase: Marked as improvement because the compare was 5% less than the baseline, and the value was not too small.
IsImprovementCheck: Marked as improvement because the three check build points were 0.05 less than the baseline.
IsImprovementWindowed:Marked as improvement because 257.4118074 < 301.34383597333334.
IsChangePoint: Marked as a change because one of 1/11/2022 2:18:34 PM, 1/18/2022 5:19:20 AM falls between 1/8/2022 8:22:56 PM and 1/18/2022 5:19:20 AM.
IsImprovementStdDev: Marked as improvement because 126.84958808128651 (T) = (0 -257061351.36344) / Math.Sqrt((29015167390259.09 / (299)) + (4509478591652.629 / (34))) is greater than 1.9671567996108528 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (34) - 2, .975) and 0.19125696107618467 = (317852938.4382813 - 257061351.36344) / 317852938.4382813 is greater than 0.05.
IsChangeEdgeDetector: Marked as regression because Edge Detector said so.
